A method for providing control power for an electricity network in which at least one energy store connected to the electricity network supplies energy to the electricity network as required and/or takes up energy from the electricity network as required, the control power being delivered in dependence on a frequency deviation from a setpoint value of a network frequency, tolerance with respect to the amount of the control power to be provided being used to set a charging state of the energy store at a same time as providing control power by the energy store. A device for carrying out such a method includes a control system and an energy store, the device being connected or connectable to an electricity network, the control system being connected to the energy store and controlling control power given off and/or taken up by the energy store.

Method for providing control power by an energy store by using tolerances in the delivery of power

A method providing control power for an electricity network in which at least one energy store supplies energy to the electricity network and/or takes up energy from the electricity network dependent on a frequency deviation from a desired frequency of the electricity network, a deadband being prescribed around the desired frequency. The frequency deviation from the network frequency is measured with greater accuracy than a width of the deadband and a bandwidth within the deadband is chosen dependent on a charging state of the energy store, with control power being provided outside the bandwidth. A device carrying out the method includes at least one energy store and a control system controlling control power of the energy store in an open-loop or closed-loop manner, the energy store being connected to an electricity network such that energy can be fed into the electricity network and can be removed from the electricity network.

Method for providing control power using an energy store having variable deadband width when providing the control power

A method for providing control power for an electricity network in which at least one energy store connected to the electricity network supplies energy to the electricity network as required and/or takes up energy from the electricity network as required, the control power being delivered in dependence on a frequency deviation from a setpoint value of a network frequency, a tolerance with respect to the frequency deviation being used to set a charging state of the energy store at a same time as providing the control power by the energy store. A device for carrying out such a method includes a control system and an energy store, the device being connected or connectable to an electricity network, the control system being connected to the energy store and controlling the control power that is given off and/or taken up by the energy store.
